Has anyone read the Pistis Sophia? What are you're impressions?

Pistis Sophia is an important Gnostic text, possibly written as early as the Second Century. The five remaining copies, which scholars place in the Fifth or Sixth Centuries, relate the Gnostic teachings of the transfigured Jesus to the embled disciples (including his mother Mary, Mary Magdalene, and Martha), when the risen Christ had accomplished eleven years speaking with his disciples. In it the complex structures and hierarchies of heaven familiar in Gnostic teachings are revealed.
